Software patterns will provide mature soluitons to common software problems. They are abstraction ofsoftware domain knowledge and their use realizes the reuse and sharing of software domain knowledge. Based on theintroduction and analysis of the primary situation of pattern research in the software domain,this paper reveals the ne-cessity and importance of pattern reseach.
Process pattern is an excellent method to express software process knowledge, it can express processknowledge in different granularity and realize the non-gap connection of process knowledge, it supports the reuse andpersistent improvement of process knowledge. In this paper, we put forward a process Pattern Based Software Pro-cess Framework(PB-SPF), its three layer architecture has realized the high abstraction of software process and theseparation of its contents, so it have good reusability and adaptability. We can use it as a base for the research of soft-ware process, the building and enactment of process model.
